6e938c74
TC
56 - the font has_chars() method now returns perl's true and false

75 - we rely on Config.pm's d_vsnprintf as to whether we use
76 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
77 though it only has _ prefixed versions of these. Define our own
78 prefixed names on Win32.

6d5c85a2 88==============
a7e32beb
TC
89
90 - add simple tests for the Imager::Test test_image generators
91
6d5c85a2
TC
92 - io_glue I/O buffering re-work:
93
94 - reorganize io_glue to do it's own buffering by default
95
96 - the unbuffered functions are available as i_io_raw_read() (or
97 raw_read() from perl) etc but are not recommended for typical
98 use.
99
100 - use the new i_io_peekn() when checking for file magic to avoid
101 seek, allowing Imager to detect the file type and read the file
102 from an unseekable stream (for formats that don't use random
103 access)
104
105 - added several new I/O layer API functions.
106
107 - fix the TGA performance problem, most noticably on Win32
108 https://rt.cpan.org/Ticket/Display.html?id=70037
109
110 - TIFF now uses wrapper functions of the correct types to avoid casts
111 https://rt.cpan.org/Ticket/Display.html?id=69912
112
113 - the callback IO object did its own buffering, controlled by the
114 maxbuffer parameter supplied to the read() and write() methods.
115 This buffering has been removed, to avoid redundancy with the
116 common io_glue buffering. This also avoids a bug in that code
117 which could rarely pass a zero length to the read callback and
118 then panic about the result.
119
120 - the callback IO object now tests the result of calling the close
121 callback, which should return true for success.
122
123 - the PNM reader did its own buffering. This buffering has been
124 removed to avoid redundancy with the common io_glue buffering.
125
126 - previously the read handlers for fd and callback I/O layers would
127 call the underlying interface (POSIX read or your supplied callback)
128 until it filled the buffer. It now only makes one call.
129
130 - added public constructors for I/O layer objects (see Imager::IO)
131
132 - all core file handlers now use the i_io_foo() wrappers to gain
133 access to buffered I/O rather than calling the I/O layer
134 callbacks directly.
135
136 - all core file handlers now check for error on close.
137
138 - Backward compatibility: if you hava custom file handlers, you can
139 use i_io_write() etc since they're available as macros in older
140 versions of Imager.
141
142 - eliminate the final remnants of io_glue_commit_types().
143
144 - bump IMAGER_API_VERSION, since the above may break assumptions.
145
146 - removed the long unused i_gen_reader() and i_gen_writer() utility
147 functions.

TC
150===========
151
0c647c9a
TC
152The main changes in the release versus 0.84 are:
153
154 - on 64-bit systems, 64-bit types are consistently used for image
155 dimensions and co-ordinated, and for memory block sizes.
156
157 - handle IFD loops in TIFF files correctly. Previously this would
158 lead to an infinite loop.
159
6ad7e4bc
TC
160Bug fixes:

TC
169
170Bug fixes:
171
172 - the image file limits set by set_file_limits() weren't being
173 checked when reading TIFF files.
174 https://rt.cpan.org/Ticket/Display.html?id=69915
175
5970bd39
TC
176 - Provide more information about file format module load errors on a
177 failed image file read() or write().
178 https://rt.cpan.org/Ticket/Display.html?id=69194
179
4ce3551c
TC
180 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
181 through TIFF images, since it checks for IFD loops.
182 https://rt.cpan.org/Ticket/Display.html?id=69914
183
a16bca6d
TC
184 - don't leak memory when out of range palette indexes are supplied to
185 setscanline().
186 https://rt.cpan.org/Ticket/Display.html?id=69242
187
188 - require a later version of CPAN::Meta to ensure JSON::PP and
189 CPAN::Meta::YAML are available.
190 https://rt.cpan.org/Ticket/Display.html?id=69008
191
ac575c5f
TC
192 - hoist the per-line calculations for the flines implementations, and
193 modernize the tests a bit.
194 https://rt.cpan.org/Ticket/Display.html?id=70126
195
86c8d19a
TC
196 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use

207Imager 0.84_01 - 8 Aug 2011
208==============
209
210Development release as a sanity check for the types re-work.
8d14daab
TC
211
212Massive types re-work:
213
214 - the type used internally for pixel co-ordinates and image sizes is
215 now 64-bit on 64-bit platforms (at least sane ones).
216
217 - size_t is now used consistently for memory block sizes.
218
219 - since this changes the binary interface, the Imager API version has
220 been incremented. Any module that uses the API will need to be
221 rebuilt. In most cases that will be enough, but calls to any APIs
222 that take a pointer to image sizes may need source changes.
223
224 - you should be able to create very large images on 64-bit systems,
225 if you have enough memory. Successfully created a 32768 x 49192 x
226 3 channel image, filled with a tiled image and scaled it. The
227 unscaled image was also successfully saved to a JPEG.
228
229 - check the image size before attempting to write BMP, GIF, JPEG,
230 PNG, SGI, TGA, TIFF images.
231
232 - correctly handle reading TGA images over 32767 pixels wide or tall.
233
234Incidental changes:
235
236 - the gif_left and gif_top tags are now clamped to non-negative
237 values when writing a GIF image.
238
239 - removed dead callback read/write code
240
241The default maximum memory size when reading files is now 1G.

247 old, old perl.
248

TC
268 - convert colors to grayscale if the supplied (or generated) palette
269 contains only grays when performing error diffusion color
270 translation.
271 https://rt.cpan.org/Ticket/Display.html?id=68508
272
59c150a4
TC
273 - writing a paletted image to GIF wouldn't always use the colors
274 supplied (or generated, eg. via make_colors => "mono"), which was
275 confusing at best.
276 https://rt.cpan.org/Ticket/Display.html?id=67912
277
5b480b14
TC
278 - replace (imager|tony)@imager.perl.org in the doc, since I don't

302 - compose() with the target, source or mask position off the top or
303 left of the target image didn't clip the source image correctly.

305
306 - compose() now returns a useful error message on a non-positive
307 opacity.
308
309 - compose.im now at 100% test coverage. (As opposed to, umm, much,
310 much less.)

TC
313===========
314
315Bug fixes:
316
317 - eliminate calls to i_has_format() from the test suite, since it's
318 no longer a useful way to check for file format support. Eliminate
319 i_has_format() from the functions exposed via XS.
320 https://rt.cpan.org/Ticket/Display.html?id=65863
321
7540f84a
TC
322 - eliminate calls to note(), which isn't in the (very old) version of
323 Test::More we have as a pre-requisite. note() is modern enough
324 that I don't feel a need to require a Test::More upgrade for it.
325 https://rt.cpan.org/Ticket/Display.html?id=65864

337 downgrade the version in this file.
338 https://rt.cpan.org/Ticket/Display.html?id=66250
339
340 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
341 that option for the directories that would normally go in
342 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

419 - the convert() method now optimizes the case where all output
420 channels are either 0, sourced from a single input channel or 1.

942 - some TGA images weren't being detected correctly as TGA images
943 https://rt.cpan.org/Ticket/Display.html?id=32925
944
945 - handling of the left-over bit for 16-bit/pixel TGA images has been
946 changed to match the behaviour of the GIMP. Previously the bit
947 being set was treated as an opaque pixel, but one user reported a
948 problem with loading such an image. I haven't been able to find any
949 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
950 I'll match it's behaviour. See issue 114913 in the GIMP's
951 bugzilla.

1274Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1275

1280 http://rt.cpan.org/Ticket/Display.html?id=22166

1285 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1286
1287 - fills.c was failing to compile on Solaris 10 (compiler unknown)

1291 the file correctly
1292 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1293
1294 - gif.c was failing to build under MSVC
1295 http://rt.cpan.org/Ticket/Display.html?id=23922
1296
1297 - in some cases strings passed to the string() method were treated as
1298 terminated by NUL (chr 0)
1299 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1300
1301 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1302 that's the default build name for zlib on Win32.
1303 http://rt.cpan.org/Ticket/Display.html?id=23064
1304
1305 - search $Config{incpath} for headers too, which we should have been
1306 doing all along.
1307

1309
1310 - the global descent value from bounding box was the wrong sign
1311 http://www.cpanforum.com/threads/3276
1312

1316
1317Imager 0.54 - 14 Sep 2006
1318===========
1319
1320This is primarily a feature release:
1321
1322 - a new qtype value 'mixing' has been added to the scale()
1323 method. This is faster than 'normal', slower than 'preview'. This
1324 is based on the method used by pnmscale, and seems to produce less
1325 blurry results than normal.
1326 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1327
1328 - the rubthrough() method can now render onto images with an alpha
1329 channel.
1330 http://rt.cpan.org/Ticket/Display.html?id=20678
1331
1332 - the read_multi() method now falls back to calling doing a single
1333 image read via the read() method and write_multi() will now fall
1334 back to calling write() if a single image is supplied. This means
1335 you can simply call the read_multi() or write_multi() functions
1336 without having to check if the type is formatted by that method.
1337 http://rt.cpan.org/Ticket/Display.html?id=19457
1338 http://rt.cpan.org/Ticket/Display.html?id=19458

1340 - the GIF loop extension can now be written. If you don't have
1341 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1342 should upgrade.

1358
1359This is a bugfix release.

1367Imager 0.52 - 25 Jul 2006
1368===========
1369
1370This is primarily a feature release, but contains a fair few bug
1371fixes, new features:
1372
1373 - ability to read and write MS Windows ICO and CUR files
1374
1375 - you can now add file format plugins to support new file formats
1376
1377 - add POD coverage tests
1378
1379 - setcolors() and addcolors() now accept color names and so on
1380 instead of requiring Imager::Color objects.
1381 http://rt.cpan.org/Ticket/Display.html?id=20056
1382
1383 - flood_fill() can now fill to a specified border color instead of
1384 just to the area the same color as the seed.
1385 http://rt.cpan.org/Ticket/Display.html?id=19618
1386
1387
1388Bug fixes:
1389
1390 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1391 calculating the advance width.
1392 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1393
1394 - bounding_box for the T1 driver wasn't including leading and
1395 trailing spaces in the bounding box as the other drivers did, it also
1396 produced strange results for empty strings or strings containing only
1397 spaces
1398
1399 - when reading CMYK jpeg images they were being transferred to the
1400 image object as is, producing a four channel image. It only looked ok
1401 due to an old still unfixed Photoshop bug. We now convert from the
1402 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1403 http://rt.cpan.org/Ticket/Display.html?id=20416
1404
1405 - reading a CYMK TIFF would result in a 4 channel image, reading any
1406 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1407 result in an error.
1408 http://rt.cpan.org/Ticket/Display.html?id=20415
1409
1410 - added /usr/local/include to the default include search path, since
1411 we were already searching /usr/local/lib for libraries.
1412
1413And various minor fixes and documentation updates.
